Quiet thread. Has anyone using 122 experienced or noticed anything new or different or better? Running it as my primary now, and haven't found anything at all.

Selection is lacking though and lack of uBlock Origin means pass.
For home use I would recommend getting Pihole on a raspberry pi or other stationary device.
No need to install adblockers on any device and it works really well.

Could also be used outside home if you create a VPN server (ex Wireguard) in your home network and connect to that in public hotspots etc.
